This video is just fabulous-Thank you to the person who posted it. How wonderful to have all this information, from all these amazing first generation Ashtangi-So much shared knowledge and wisdom and not an asana in sight.
The Basics of Pranayama Yoga with Richard Freeman. I found this a really interesting clip on pranayama. Richard touches briefly on Mula bandha too (very briefly, but quite specifically). He seems like quite a chracter. Enjoy!
